KTeV KL -> pi0 mu mu plots

"Search for the Decay KL ->
pi0 mu+mu-"

m_vs_pt.eps
Reconstructed PT2 vs m after all other selection criteria, for the data. The box indicates the signal region; events in the lower left are predominantly KL->pi+pi-pi0 with pi+- decays in flight.
-------------------------------------------------------

m.eps
Reconstructed m after all other selection criteria, for the data (dots), and the total background estimate (line). The arrows indicate the range of values of m accepted. The small bump in the background at the KL mass is from KL->mu+mu-gamma gamma.
